Variable Displacement Axial Piston Pumps PVC Series
- Displacement 18 ... 71 cmᶟ/rev
- Rated pressure 280 bar
- Maximum pressure 350 bar
- Tandem capability SAE standard
PVC Series variable-displacement axial piston pumps: PVC18, PVC28, PVC45, PVC63 and PVC71 are designed for hydraulic systems of mobile machinery. Their compact design, reduced energy consumption, wide range of control systems and configuration options allow the pumps to be adapted to different machine types and operating conditions.
Applications: telescopic handlers and backhoe loaders, wheel loaders, bulldozers, articulated boom lifts, combine harvesters, cranes, as well as other construction, forestry, agricultural and special-purpose mobile machinery.
According to the applicable technical specifications (TU), Hydrosila products are not classified as dual-use products.
PVC Series pumps combine a compact and reliable design with a wide range of control options. Different types of controllers make it possible to maintain the required pressure and flow parameters according to the requirements of a specific hydraulic system.
The cast-iron housing contributes to efficient heat dissipation, while the optimized design of the rotating group ensures stable operation, high volumetric efficiency and reduced energy consumption. The pumps can be used in construction, forestry, agricultural and municipal machinery, material-handling equipment, as well as in machines for the mining and oil and gas industries.
Features:
- axial piston swashplate design;
- variable displacement;
- high volumetric efficiency;
- smooth operation over a wide speed range;
- high-wear-resistance bimetallic valve plate;
- bushed cylinder block design of the rotating group improves the anti-friction properties of the sliding pairs and contributes to higher overall pump efficiency;
- tapered roller bearings designed to withstand significant radial and axial loads;
- mechanical retention of the cradle pivot bearings ensures reliable operation of the displacement control mechanism;
- mounting flanges in accordance with SAE standards;
- SAE tandem mounting capability.
Control options: pressure compensator; pressure and flow compensator; remote pressure compensator; electrically controlled pressure compensator.
Hydraulic fluids: mineral and special oils with a kinematic viscosity of 30...70 mm²/s at +50 °C.
The fluids must comply with DIN 51524-2.
